Answer:
For Question #8 I think it's maybe 190 square feet
Explanation:
1. Do 5*5 to find the base of the rectangular prism
2. 4*5 to find the sides of the rectangular prism
3. Do 20*4 to represent all of the side's areak
4. After do 80+25 and then find the area of the triangular prism on top of the rectangular prism which is A=1/2*bh
5. After you find the area of the triangular prism add that to 105 (which is the sum of 80+25) which is 60+105=165
6. Then find the area of the top rectangle on the rectangular prism which is 25 and add that to 165. So 165+25=190 I think
Hope I'm right and hope it helps :)
